Autism and Neuropsychology, by Marisa Marzillo Autism is a lifelong disorder that has become the discussion of many media outlets; it is a disorder that causes abnormal neurological development. It seems that lately autism prevalence is increasing, which is causing a demand for professionals to investigate on what causes autism. Autism disorder is characterized by different behavior including social impairments, difficulty in communication, and restrictive patterns of behavior. The neurobiology of politics What, if anything, should we make of studies that purport to find neurological differences between people who self-identify as "conservative" and people who self-identify as "liberal?" You've seen studies like that in the paper. You've heard them argued about on radio and TV shows. But what do they actually mean? Is this just so much high-tech phrenology?
A Theory on the Deja Vu Phenomenon A Theory on the Deja Vu or Déjà vu Phenomenon During the time while this web-page has been on the Internet, more than three thousand people (up to Nov 2009) have e-mailed to say that they have Déjà Vu experiences. That is interesting, but their descriptions have virtually always described some different phenomenon. If a person has any pre-knowledge of something that is yet to happen, like in a dream, it cannot be Déjà Vu, and is likely to be some type of Precognition. (Even if the Precognition is only a few seconds before the event.) How To Boost Brain Power and Memory Until just a few years ago, doctors believed that the brain stopped making new neural connections - meaning that the memory began to get irreversibly worse - when the body stopped developing, usually in the early 20s. And doctors knew that, like any other part of the body, neurons weaken as people age. Loss of brain function due to neural breakdown was assumed to be a normal, unavoidable part of aging.
Chapter 12: Attention and Consciousness Attention involves top-down (voluntary) goal-directed processes and bottom-up (reflexive), stimulus-driven mechanisms. They influence the way information is processed in the brain and can occur early during sensory processing. Balint's syndrome is a visual attention and awareness deficit. Someone who has this syndrome can only perceive one object at a time. Theoretical Models of AttentionAttention is defined as the ability to attend to somethings while ignoring others. There are three principle goals:To understand how attention enables and influences the detection, perception and encoding of stimulus events as well as the generation of actions based on the stimuli.To describe the computational processes and mechanisms that enable these effects.To uncover how these mechanisms are implemented in the brain's neuronal circuits and neural systems.
Dream facts Dreaming is one of the most mysterious experiences in our lives. During the Roman Era, some dreams were submitted to the Roman Senate for analysis and dream interpretation. They were thought to be messages from the gods.

Within the category of small molecule neurotransmitters, the biogenic amines (dopamine, noradrenaline, serotonin and histamine) are often referred to as a discrete group because of their similarity in terms of their chemical properties.

How Our Brains Make Memories Sitting at a sidewalk café in Montreal on a sunny morning, Karim Nader recalls the day eight years earlier when two planes slammed into the twin towers of the World Trade Center. He lights a cigarette and waves his hands in the air to sketch the scene. At the time of the attack, Nader was a postdoctoral researcher at New York University. He flipped the radio on while getting ready to go to work and heard the banter of the morning disc jockeys turn panicky as they related the events unfolding in Lower Manhattan. Nader ran to the roof of his apartment building, where he had a view of the towers less than two miles away.
The Brain—Information about the Brain 1 Introduction “I think, therefore I am.” —René Descartes, 17th-century philosopher Few of us question the crucial importance of the brain. It is vital to our existence. Our brains enable us to think, as René Descartes so skillfully pointed out nearly 400 years ago.
